How long should an H3 prompt be?
Use enough detail to define one shot. A focused sentence or short paragraph is usually more useful than a scene-by-scene script.
Prompt library / MiniMax H3
Write a shot, not a synopsis.
Cinematic prompting becomes more reliable when every phrase belongs to the same shot. Start with the subject and visible action, then place the camera, describe the light, and close with the emotional temperature.
H3 motion reference
Framing and pacing study
Where this works
This structure works for drama, science fiction, suspense, and poetic short-form footage. Remove adjectives that do not change something visible in the frame.
Ready-to-use prompt
A lone cyclist crosses a rain-soaked bridge at blue hour, low tracking camera moving parallel to the wheels, sodium lights reflected in the road, distant traffic softened by mist, restrained cinematic tension, natural motion blur
Three controls that matter.
01
Subject plus visible action
02
One camera move
03
Light and mood that agree
Questions, answered.
Should I name camera lenses?
Use lens language only when it changes framing or depth. Plain camera direction is often clearer.
